Volunteers with NOAA’s Phytoplankton Monitoring Network have reported a bloom of the diatom, Pseudo-nitzschia in Galveston Bay, Texas, and NOAA’s Analytical Response Team has confirmed that the bloom is producing domoic acid, a neurotoxin that can cause amnesiac shellfish poisoning. State managers of the Texas Parks and Wildlife Department and Texas Department of State Health Services have been notified of the toxic bloom.
